AO. G. NEWTON, OF EDINBURG, MISSOURI.

Letters Patent No. 83,530, dated October- 27, 1868.

The Schedule referred to in these Letters' Patent and making part of thesame.

To all whom t 'ma/y concern l Be it known that I, O. G. NEWTON, ofEdinburg,

in the county of Grundy, and State of Missouri, have invented a new anduseful `Improvement in vTuyeres: and I do hereby-declare that thefollowing is a full, clear, and exact description thereof, which willenable those skilled in the art to make and use the saine, refereneebeing had to the accompanying drawings, forniing part of thisspecification. l

The object of this invention is` to provide an irnprovement in tuyeres,whereby the cinder may be more readily removed and theblast regulated,than can be done with those now in use.

It consists of a ball-valve, provided with cavities to receive thecinder, arranged on a rotary shaft, having a vertically-adjustablebearing, whereby it can be readily raised and .lowered-to beY rotated`for thedischarge of the cinder, and also for regulating the passage ofair to the lire.

Figure 1 represents a sectional elevation of my improved tuyere, and

Figure 2 represents a plan View of the same, with the cap removed.

Similailetters of reference indicate corresponding parts.

A represents the air-vessel, of which Bis the cover, provided With theusual opening, 0, for the air topass to the iire. I

D represents a weighted valve at the bottom ofthe air-vessel, forregulating the blast, and for vthe discharge of ashes and cinders.

E represents the ball-valve, provided with the concavities F for thereception of thelcinders, and which is supported axially on thehorizontal shaft G, having bearing in an adjustablev slide, H, and alsoin the 0pposite side ofthe air-vessel A.

Theshait G is prolonged a sutcient distance to be provided'on its end,outside of the Walls of the forge, with a crank, I, for turning it.

The'slide H may be tted to operate in the groove provided for it, withsufficient friction to maintain the shaft G in any position desired, orit may be provided with other means for holding it.

By this means the air-blast may be readily regulated and adjusted asrequired, and `the fire may be with equal facility cleaned of cindersand other foul latter, by lowering and turning the valve to dischargethe cinders below, the blast maintaining the .re in itsposition, andirolnfalling down withthe valve.

I am aware that the devices, marked in the drawing A, B, E,'F, and G,are not new, but are found in the patent of J. Lubach, November 10,1841, and I do not claim them separately; but

What I do claim isl The combination of those parts With'the adjustable`bearing for the shaft G, as arranged and described;

'Ihe above specification of my invention signed by me, this 3d day ofJuly, 1868.

O. G. NEWTON.
